The only Malay specimen available is a poor one, with small umbels and flowers 

 smaller than in the usual Indian forms, but the structure agrees with the latter. 



23. PERauLARiA, Linn. 

 Twining shrubs. Leaves opposite. Flowers of moderate size, 

 numerous, in pedunculate or subsessile umbelliform cymes, lateral 

 between the bases of the petioles. Calyx 5-partite; scales within 5 or 

 none. Corolla hj^ocrateriform ; tube inflated at the base ; lobes 5, 

 erect, overlapping to the right. Corona of 5 erect processes arising 

 from the base of the staminal-column and adnate to it in the lower 

 part, free above and with a narrow or subulate process on the inner 

 face. Staminal-column arising from the base of the corolla ; anthers 

 oblong, erect, with long erect membranous appendages conniving over 

 the apex of the style ; pollen-masses solitary in each anther-cell, erect, 

 attached in pairs to the pollen-carriers by very short caudicles. Ovary 

 of 2 carpels ; style not exceeding the anther-appendages ; style-apex 

 stout, ovoid-pentagonal. Follicles lanceolate, terete, rather turgid. 

 Seeds ovate, concave, comose. — Distrib. About 10 species, chiefly
